I am sexually active with my husband frequently. We aren't trying for kids as he thinks it isn't the right timing, and I agree, but I wouldn't be mad if we had a "happy little accident" to quote Bob Ross. I usually chart my discharge, so I know what's regular for me. I'm supposed to start my period tomorrow, and I got a weird discharge today that was a glob of clear sticky mucous with something brown in the center which I assumed was blood. I've never gotten this before. Is this period or pregnancy related?
